Problem Info

During the spring and summer, tiny black biting midges 1/25 to 1/8 inch long infest the yard. They are most common in coastal areas and near lakes, streams, marshlands, and swamps. These annoying insects are also known as no-see-ums, sand flies, or black gnats. They feed on warm-blooded animals, including humans.

Solution Advice

Apply insect repellents, available at drugstores, to the skin. The bites are rarely painful but produce tiny swellings or blisters that continue to itch for several days.
